Re-reading my last post, I see that I have, without meaning to, implied that the production BC26 can't be a good looking boat.  I did not mean that!  It is a good-looking boat, it really is.  Just not quite as pretty as the prototype in those magazine photos.

OP, as you've already experienced both a Shrimper and a Red Fox, seems to me you'll have a good idea of what to expect?

My BC 26 is a pre production prototype and, imho, very much in the Shrimper/Crabber camp as regards being a small sailer that is trailerable. Mine not a trailer sailer...at least to me! Current BC 26s differ in configuration.

The unknown here seems to be what exactly is the configuration of an inboard BC23? Shaft or Sail drive? Legs required to dry out?
Mine sits on a sort of tripod, formed by the keel bulb (drop keel, not centreboard type arrangement) and the two rudder stocks. The yard did not recommend that I left it on a semi drying mooring full-time, it's  very hard on the boat (hence it lives permanently afloat).
I'd be surprised  if an inboard BC23 dries out like this? Maybe a shaft drive exiting via a small skeg is tucked up enough for it to sit on its hull bottom? Anyone have photos please?

That said, where I live many Crabbers, Shrimpers, Cape Cutter even a Golant Gaffer and the like do regularly dry out here. Some require beaching legs. Some old "banger boats" appear not to even bother with legs (when obvioulsy they really should) and still survive years...
However, in the 35 years I've been watching this river, I've seen bilge keel Centaurs and a Southerly lift keeler sunk by conflabs with their mooring chains! The very lovely Golant Gaffer didn't  stay long....even here in Golant!

My first boat was a Norfolk Gypsy with a Yanmar 10hp inboard https://www.neilthompsonboats.co.uk/preowned/norfolk-gypsy-turaco/.  This is the same boat that I owned - she had a navy blue hull when I had her.  Although the same length as the BayRaider, she weighed nearly three times as much and was reassuringly solid.

As with the BC26 mentioned above, I never intended to use her as a trailerable day sailer, flitting from place to place.  But she could be towed to a new sailing area at the start of each season, before boredom had a chance to set in.  That involved a tow car with a large engine (a Vauxhall Senator) and finding a new secure mooring each year, usually a marina with pontoons.  An expensive way of going about things with a relatively small boat and this was the reason why I eventually sold her.  On the other hand, secondhand values for older Gypsies have tended to rise rather than fall, compensating for sometimes eye-watering operating costs.

Voting has now closed and our ambitions for use in 2024 are greater than our actual use in 2023.  None of the respondents plan for only a little use this year but illness, family obligations and work can get in the way.  I expected to be in the 16-30 day range but bad weather has already knocked three days off my plans.

A few thoughts, fwiw? My BC 26 is inboard diesel, saildrive.

extra weight....yes undoubtedly.
no ability to dry out.... Not so. I can, and do dry out. However, need to be very aware of the vulnerable saildrive.
extra drag when sailing. ...Not too bad. Saildrive aperture has a fairing diaphragm.  Folding prop.
loss of space...yes.
hassle of anodes etc...yes, especially  on a Beta Marine diesel/twin disc drive leg. They eat anodes (lots of dissimilar metals). Fortunately,  as a Marine Engineer I do my own maintenance, in situ of of course.
trailer needs greater immersion, including hubs...yes, very much so. Immersing a double axle braked trailer can quickly/easily become very expensive and time consuming. My trailer has never been in the water, the boat being moved by a yard hoist and placed on the trailer, mast up. Original owner used to take the mast down (alloy - so crane required), then tow home behind a Land Rover for barn storage.  I have neither LR, nor barn; she lives in a yard near home. As before, the boat is launched in the spring, and recovered in the autumn.
My Storage fees include over-summering the trailer. It is too big/heavy to move by hand.

For me, the drying out issue is important, and, as I want to launch / recover the boat myself rather than pay for craneage, the trailer immersion is critical too.
...Yes... to me, the owners planned routine/cycle of usage is the key driver in "acceptability " of an inboard? Now in my 2nd season, it definitely works for me. Quiet, very economical, reliable, always immediately available (as is the fuel, there are several ports hereabouts where "bulk petrol" is not readily available.

Other things?
Obvioulsy...Trailer/train size/weight. My trailer maybe about a Ton MT, I fear? Towed it once behind my ordinary estate car. Not something I'd want to do regularly,  it definitely had control of the car. With boat loaded, it would be over 10m long (not that I'd be able to move it with the car, even if stupid enough to try)!
Years ago, as a group of pals, we campaigned an International 6m (almost 40ft, maybe 8T - perhaps more?) Towing a tri-axle trailer behind a very large US Ford F650 double rear wheel pick up. Towing to France decided for me that it was NOT the sort of thing that I wanted to do for a "holiday". This gets complicated,  and VERY expensive. Nerve wracking! Wealthier owners use especially converted 7.5 T flat bed lorries, towing the support rhib on a trailer. The very wealthiest,  adapted curtain side artics, and have "a chap" to do the work! It's  all possible -what is your budget!?

Towing a BC 23 might be about my personal limit, in financial/commitment terms (needs a bigger car, more fuel, more "admin") and in terms of "nerve"?

However, I'm  fortunate,  in that I have pals with boats based in both Scilly and W Scotland, so no need to tow mine!

So...maybe don't dismiss an inboard, should one turn up - it might suit? But,  As far as I know, there are very few.
